Parameter: Jp
Definition
Strength of the pair-hopping term in the interaction term, $J_p$.
Type
Float, double precision
Default value
0.0
Component
ALL
Behavior
In principle, it is used to build the Coulomb interaction matrix.
But the NARCISSUS component does not support general interaction. In other words, it does not support the $J_p$ term in the local impurity Hamiltonian.
As for the MANJUSHAKA component, the Coulomb interaction matrix is not built within the quantum impurity solvers. All of the information is encapsulated in the atom.cix file. So they don't need the $J_p$ parameter as well.
So, in summary, we don't use this parameter actually. You can set it to any values as you wish. But we strongly suggest to set it to the exact value.
